Cut the beef into very thin strips (partially frozen helps a lot), and marinade overnight. Pat dry and dehydrate!

This is not Outrageously hot, but certainly enough to make it completely avoided by my non-Ch friends (pathetic masses....), and really big hit on a white-water rafting trip with a boat-load of thrill-seekers. I really liked the pineapple, but you could probably use just about any acidic fruit juice.
